Question

Ва→Ва(ОН)2→Ва(НО3)2→ВаСО3→ВаСl2​

Answer 1

Ответ:

Объяснение:

Ba + 2H2O = Ba(OH)2 + H2

Ba(OH)2 + 2HNO3 = Ba(NO3)2 + 2H2O

Ba(NO3)2 + Na2CO3 = BaCO3↓ + 2NaNO3

BaCO3 + 2HCl = BaCl2 + CO2↑ + H2O

Answer 2

It seems like you've provided a sequence of chemical reactions involving barium (Ba) and various compounds. Here's an interpretation of the reactions you've listed:

1. Ba → This represents barium in its elemental form.

2. Ba(OH)2 → Barium hydroxide. Barium reacts with water to form barium hydroxide, Ba(OH)2.

3. Ba(NO3)2 → Barium nitrate. Barium hydroxide (Ba(OH)2) can react with nitric acid (HNO3) to form barium nitrate (Ba(NO3)2) and water (H2O).

4. BaCO3 → Barium carbonate. Barium nitrate (Ba(NO3)2) can undergo a double displacement reaction with sodium carbonate (Na2CO3) to form barium carbonate (BaCO3), sodium nitrate (NaNO3), and carbon dioxide (CO2).

5. BaCl2 → Barium chloride. Barium carbonate (BaCO3) can react with hydrochloric acid (HCl) to produce barium chloride (BaCl2), water (H2O), and carbon dioxide (CO2).

Each arrow represents a chemical reaction or a transformation of the substances involved. If you have any specific questions about these reactions or if you need more information about any of the steps, please feel free to ask!
